Is KuCoin connected to Binance?

Could you elaborate on the potential connection between KuCoin and Binance? I've noticed some similarities in their services and operations, but is there a formal partnership or affiliation between the two? Are they competitors in the same market segment, or do they occupy different niches within the cryptocurrency exchange landscape? Clarifying this relationship would help me better understand the positioning and strategy of both platforms. Thank you for your assistance in clarifying this matter.
